Be' it known that I, CARLIsLE FORREST SMITH, a citizen-ofthe United States,'and a in the county of Howard and State of Indiana, have invented certain new and useful Improvements in Carbureted- ,onnnunErED-rum. snrana'ron i Specification of Letters latent.

Fuel Separators and Fuel-Vaporizers, of

which the following is a specification.

My present invention relates ge'nerallyto devices located between the carburetor and .working cylinders of an internal combustion engine for treating the carbureted fuel supply, and is in particular a device for separating unbroken portions of liquid fuel from 15 that portion of the fuel consisting of well broken particles suspended in and carriedgiy the air, and my object is to increase the e ciency of internal combustion engines by so separating the fuel and subjecting the heavie particles of liquid alone to the vaporizing action of a heated surface.

More especially the use of means in connection with an intake and exhaust manifold ceive and separate fuel flowing from a carbureter to the extent of withdrawing heavier particles and unbroken portions of fluid my invention contemplates.

whereby to re-- from thewell broken particles suspended inthe air which pass on to the intake ports, the heavier particles of unbroken fluld so separated, falling upon a surface heated by the exhaust gases so as to vaporize the same inorder that they may rise into and join with the flow of well broken fuel.

In the accompanying drawings which illustrate the referred form of construction conceived by my invention and which forms a part of this specification,

Figure 1 is a front elevation of the device complete,

Fig. 2' is an end view, Fig.3 is a side view of the carbureted fuel p Flg. 4 is a front elevatlon of the central portion of the apparatus with the fuel pipe removed, and

Oct. 25-, 1921.

Adjacent to the central portion of the combined manifold is an enlargement, the front wall l3 of which is separated from the exhaust passage 14 as seen in Fig. 5, by means of a vertical wall 15 forming a vaporizmg well 16 between this internal wall 15- and the front wall 13, this well being in communication at its upper portion with the inlet passage 17 of the manifold, and below a series of verticalribs 18 disposed o posite to the intake opening 19, the latterof receive carbureted fuel from a fuel supply pipe 20, leading in practise from a carbureter. 1

As shown in Fig. 5, the internal wall 15 is fluted or ribbed at its lower portion in order to withdraw maximum heat from the exhaust gas in the passage 11 and radiate maximum heat into the liquid within the vaporizing well '16 to which the liquid falls from the ribs 18.

with the intake passage 17 of the manifold, as shown.

The flanged upper end 21 of the fuel feed pipe 20' is secured, b bolts 22 or any other suitable manner to th intake opening 19 and municatlng with the manifold a short delivery tube 23 as best seen in Fig. 5, having at one end, within the pipe 20, an annular ex ternal groove 24: the purpose of which is to entrap any unvaporized fuel passing upwardly along the inner surface of the The pipe is also provided with a downwardly and inwardly inclined opening 25 Whose upper end communicates with the groove 24 and whose lower end communicates with the upper portion of the vaporizing well 16 so that the liquid entrapped izing well.

It is thus obvious that carbureted fuel ipe 20 to themani'fold' passing through the will strike the ribbe wall 18 of the manifold opposite its intake opening,--as will be plainly seen by a comparison of Figs. 4 and '5, that portion of the fuel which contains well broken particles of fluid suspended in "the air being free to pass to opposite sides of the ribbed wall and thus into the, intake passage 17 of the manifold.

It will be observed, however, that such particles of. fluid as "are not sufliciently broken to be carried by the air after impingement against the ribbed wall 18 which e manifold around itscarries 1n its end compipe.

, will At opposite sides of the ribs 18 the. lntake opening 19 is .in communication '24 will fall into the vaportravel down the same and fall into the vaporizing well 16 and thus against or in close proximity to the exhaust heated wall 15.

rangement wherein the properly broken up particles of fuel are free to pass into the working cylinders along with the air, this being the ideal condition of the fuel from thestandpoint of economy and efficiency. Only those portions of the fuel, namely, the

heavier improperly broken particles of fuel I are acted upon and vaporized, which if.

passed directly into the working cylinders would set up an uneconomical and inefficient result, and my invention thus avoids the disadvantages of known fuel feeding apparatus without sacrificing any of the advantages thereof which are commonly incident thereto.

I claim 1. A manifold having an intake opening, a bafile opposite the intake opening, means formin a va orizing well below and into which-t 1e ba e drains, provided with an exhaust heated wall, a fuel'feed pipe attached to the manifold and a fuel intake tube extending from the adjacent end of the pipe and projecting into the intake opening of the manifold toward and at right angles to the said bafiie.

2. A manifold having an intake opening, a vertical baffle opposite the intake opening, means forming a vaporizing well below and into which the baffle drains, provided with an exhaust heated wall, a fuel feed pipe attached to the manifold and a fuel intake tube extending from the adjacent end of the pipe and projecting into the intake opening of the manifold toward and at right angles to the said bafile, said tube having an external annular groove within the fuel pipe, and said fuel pipe being provided with apassage in communication between the lower portion of the said groove and the upper portion of the said vaporizing well.

3. A manifold having intake and exhaust passages, and an intake opening leading horizontally into the intake passage at right angles thereto, said manifold having a vertical wall provided with vertical ribs opposite the intake opening to form a baffle, means forming a vaporizing well along a portion of the exhaust passage, opening upwardly beneath the baffle and into which the latter drains, said vaporizing well beingseparated from the exhaust passage, and in communication with the intake opening, and the intake passage, as described.

4. A manifold having intake and exhaust passages, an intake opening leading hori-. zontally into the intake passage at right angles thereto, said manifold having a wall provided with vertical ribs opposite the intake opening to form a baflie, means forming a vaporizing well along a portion of the exhaust passage, opening upwardly beneath the baflle and into which the latter drains, said vaporizing well being in communication at its upper portion with the intake opening and the intake passage, and said manifold includinga fluted wall between the exhaust passage and the vaporizing well, as described.
